В ответ на: HTML 5 video If you’re not sure what this is all about, it is all about being able to put videos on the web as easily as this: <video controls="controls" src="some.ogg"> Better to have backup content in case <a href="some.ogg">your video file</a> doesn’t work for the user. Perhaps they don’t have a nice Ogg-playing browser. Perhaps they don’t have the bandwidth for video. Perhaps they can’t see it anyway, or just choose not to. You can add a <img src="some.jpg" alt="random picture"> in the backup content, of course. </video>
File I/O Second, this release is all about being able to build applications that can run a real file system - one the user can see and play with within the application the same as they would on a local machine. This is achieved using the File I/O API we released earlier this year.
3D Canvas Third, using this build you can run cool 3D applcations created using our 3D canvas implementation, which is included in this build.
Note: 3D canvas doesn’t work on all systems. If you don’t have the right stuff in your machine this build will simply not render 3D canvas objects.
